BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a collapsible bag for carrying articles. More particularly, the invention relates to a bag that collapses into a smaller configuration.

2. Description of the Related Art

There are a variety of bags that are convertible from one configuration to another. These bags are made from materials such as nylon or cloth. For example, there are related art bags that convert from a briefcase configuration to a backpack configuration. However, related art convertible bags suffer many drawbacks. For example, when the related art bags are converted to a smaller configuration, handles may be exposed from a previous configuration. These handles may dangle, become entangled, and cause inconvenience to a user carrying the converted bag. One related art convertible bag includes a reel-like device to withdraw the handles inside the bag. The reel-like device, however, increases bag costs and prevents a larger-sized bag, upon conversion, from achieving a smaller volume than would be possible without the reel-like device.

In another example, a relatively small related art bag, such as a lunch bag or a shopping bag, may be inwardly folded for conversion into a smaller configuration for storage into a pouch. However, if a larger related art convertible bag is folded, a user may find the converted bag bulky and have great difficultly carrying the bag upon conversion into the smaller configuration.

Related art convertible bags may use a mechanical device, such as a zipper, to achieve a bag having at least two configurations. In one configuration, the related art bag is un-zipped and unfolded to realize a larger surface area bag. In another configuration, the related art bag is zipped to convert the bag to a smaller surface area configuration. Other zipper related art bags provide multiple compartments, such as form fitting slots or pockets, for storing articles of various shapes and sizes. However, the related art bags using the zipper are bulky, even upon conversion to a smaller size. Accordingly, a user is inconvenienced when transporting bag.

Thus, there is a need for an improved apparatus and method for converting a bag from one configuration to another configuration to increase a user's ability for transporting the bag, decrease storage volume occupied by the bag upon conversion into a smaller configuration, and provide other advantages over related art convertible bags.

Referring to FIG. 1, a collapsible bag 100 comprises a first wall 106, a second wall 107 and a bag receiving portion 130. The first wall 106 and the second wall 107 are substantially joined together along edges 108, 109 to form the bag. The bag receiving portion 130 is disposed, for example, proximally to an edge portion 104 along an upper portion of the first wall 106 and the second wall 107, see FIG. 2. A carrying handle 125, for example a drawstring, may be utilized for closing the bag receiving portion 130 or carrying the collapsible bag 100. A flap 105 is disposed, for example, on the first wall 106. A first zipper track 115 is disposed, for example, proximal to an edge of the flap 105. A second zipper track 120 is disposed on, for example, a lip 125 that is protruded from and attached to a portion of the first wall 106.

The collapsible bag 100, as shown in, is in a non-compressed state. The flap 105, the lip 125, and a portion of the first wall 106 form a pocket 110. First and second zipper tracks 115, 120 respectively provide an access point for opening and closing the pocket 110. A zipper slider 140 joins the first zipper track 115 and the second zipper track 120. The first zipper track 115 and the second zipper track 120 are preferably substantially parallel to each other. As shown in FIG. 1, the collapsible bag 100 is in a first configuration, having the greatest capacity for holding articles, such as consumer products, personal items, or goods, such as groceries.
